Power hitter Aaron Finch hit the roof at Etihad Stadium on Wednesday night as the red-hot Melbourne Renegades remained undefeated in the Big Bash League, romping to a seven-wicket thrashing of the Hobart Hurricanes.

Finch, the leading BBL run scorer, became the second batsman to make contact with the retractable ceiling when he smacked paceman Doug Bollinger into the rafters during the one-sided match's third over.

But the massive blow, like Mike Hussey's effort against the World XI in 2005, was controversially deemed a dead ball despite appearing to hit a support beam that was outside the boundary rope.

The Renegades killed the contest early as they tore through the Hurricanes batsmen with ridiculous ease, restricting the men in purple to a paltry 9-102, before mowing down the target just three wickets down and with 40 balls to spare.

Paceman Nathan Rimmington (3-18 from four overs) and West Indian off-spinner Marlon Samuels (3-22 from four) were the chief destroyers.

But it was the ultimate team performance from the hosts with spinners Muttiah Muralitharan (2-16) Aaron O'Brien (1-19 from four) and seamer Will Sheridan (0-6 from two powerplay overs) applying the pressure early.

The Hurricanes were a sluggish 2-35 in the eighth over which meant they had to take a kamikaze approach to the rest of their innings.

That only led to a constant flow of wickets for an end result of three fours and one six.

Ricky Ponting was the only Hobart batsman to make meaningful contribution with a run-a-ball 25 on his 38th birthday.

The veteran impressed early, reeling off two boundaries with his classic swivelling pull-shot but was bowled attempting an ambitious reverse sweep against Murali, triggering an awful collapse.

In reply, the Renegades broke the back of the run chase early.

Opener Finch finished unbeaten on 46 from 40 balls as the winners passed their target after just 13.2 overs.

The result means the Hurricanes, one of the best teams last summer, have just one win from their opening four matches.

It was also the 12th Big Bash match in a row the team batting second has won.

Worryingly for Cricket Australia it was another disappointing crowd with just 7,951 on hand to witness the one-sided affair.
